The tutorial will alternate lectures with exercises for development of a user application. The goal is to learn step by step using the Geant4 toolkit and developing of a Geant4 application. The following topics will be covered:

  • Definition of geometry and materials
  • Definition the primary particles sources
  • Definition of physical processes and selection of a physics list
  • User interfaces, macros, visualization
  • Accounting physical quantities (« scoring »), analysis
  • Multithreading
  • Biasing


  • Morning session (Monday): from  10h30 to 12h30
  • Morning sessions (Tue-Fri): from   9h00 to 12h30
  • Afternoon sessions (Mon-Thu): from 14h00 to 18h00
  • Afternoon session (Friday): from 14h00 to 16h00

Required skills

Basic level of C++ programming language is required :

  • basic/syntax: if statements, loop constructs functions, pointers, references, passing function arguments
  • classes: class definition and implementation, class data members and member functions/methods, static data members, member functions/methods, base class and derived class, pure virtual function/method
  • standard template library: iostream, vector

Geant4 Installation

The hands on will be done on the classroom computers (MAC OSX) with the Geant4 software already installed. If participants want to work with their laptops, it is necessary to install Geant4 before start of the course. No support for installation will be provided during the course.  Also no support will be provided for Windows OS.

More detailed instructions about the necessary Geant4 configuration are available here.

Social Dinner

We will organise a social dinner on Thursday (18th May) evening in the restaurant « Les saveurs sauvages », Gif sur Yvette. (The dinner will be paid by CNRS for all participants.)

Please, communicate to ivana@ipno.in2p3.fr if you intend to participate in the dinner.
